Application filed August 5, 1910. Serial No. 575,898.

To all whom it may concern:

Be it known that I, SOLOMON R. WVAGG, a citizen of the United States,residing at Appleton, in the county of Outagamie and State of Wisconsin,have invented new and useful Improvements in Driving Mechanisms forBeating-Engines, of which the following is a specification.

This invention relates to improvements in driving mechanisms for beatingengines and it has for its object to provide for a more etlicientdriving relation between the electric motor and the beater roll shaftthan is known and employed at the present time.

Originally the drive for these engines was of the pulley and belt type.This was superseded by the drive now in general use; viz., an electricmotor and a chain conneeting the motor shaft and the beater roll shaft.The disadvantages of this drive are first, a considerable oss of power;second, the necessity for frequent lubrication of the chain, practicallyabout once an hour; third, the fact that smooth running of the beaterroll is not secured; and fourth, the fact that adjustments of theposition of the beater roll, in a number of instances, provide on theone hand for too much slack in the transmission train or, on the otherhand, for too great tension. The object stated in the first paragraph issecured by the elimination of these disadvantages.

An embodiment of the invention is illustrated by way of example in theaccompanying drawings, wherein Figure 1 is a plan view showing apractical application of the improved driving mechanism; Fig. 2 is anend view partly in section; and Fig. 3 is a detail view in sideelevation and part section showing the assemblage of the bearers for theroll shaft.

Similar characters of reference designate corresponding parts throughoutthe several views.

The beating engine may be of any approved construction. In the exampleshown, the engine comprises a vat 1, separated into communicatinglongitudinal channels by a partition 2 and the beating roll 3 isarranged in one of the channels and is mounted on a shaft 4 whichextends transversely of the vat.

The engine is operated, preferably, by an electric motor 5. This motoris not connected directly to the shaft t but an intermediate train,embodying the small pinion 6 on the motor shaft 7 and the large gear 8on the shaft is employed. With a train of this character it is essentialthat the pinion G and gear 8 be held in a rigid position with respect tothe pitch line, in order to secure a quiet running of the transmis siontrain and a smooth running of the beating roller. For this purpose aspecial construction of shaft supporting means is provided at each sideof the machine. Such supporting means includes, inter alia, a U- shapedframe having a base 9 and upright standards 10 and 11 which are rigidly,preferably integrally, associated with the base. The bearings for theshaft l are arranged centrally of bearer arms 12. These extend betweenthe standards 10 and 11, their end portions projecting into slots insaid standards. The end portions of the bearer arms which are disposedin the slots of the standards 10 are pivoted. and the end portions ofsaid arms which are disposed in the slots of the standard 11 areassociated. with adjusting means to be hereafter described. The pivotsof the arms 12 are arranged in axial coincidence with the shaft 7, thepivot of the arm 12 at the right hand end of the engine comprising apin, as 13, and the pivot of the arm 12 at the left h and end of theengine comprising a sleeve 14 which surrounds the shaft 7. The standard10 at the left hand end of the engine is provided with spaced brackets15 which serve as additional supports for the shaft 7 and between whichthe pinion 6 is arranged.

The adjusting mechanism to which reference has been made may be of knownform, and, as shown, comprises a shaft 16 which extends transversely ofthe engine, passing through the standards 11 and having at one endthereof a hand wheel 17. The shaft 16 is provided with worms and theseengage with worm wheels fitted on vertical shafts 18 which are disposedin recesses or slots in the standards 11 and are threaded through asuitable extent. The threaded portions of the shafts 18 are soassociated in any desired manner with the adjacent ends of the bearerarms 12 as to produce a raising and lowering of said arms on theirpivots consequent to a corresponding rotation of the shaft 16.

The rigid association of the standards 10 and 11 with the base 9 and therelation of the bearer arms to these standards provides for the runningof the pinion 6 and gear 8 without the slightest deviation from theirpitch line in any position of the beater roll and it follows that therotation of the pinions is without noise and undue wear and that asmooth running of the beater roll is provided for under all conditions.These advantages result from the fact that it is impossible for thebearer arms to have any play or loose movement which would with draw thegear 8 from the pitch line. The assemblage of the bearer arms alsoprovides for a mathematically correct relation of the driving elementsin any position of the beater roll and eliminates the necessity of slackadjusters or equivalent arrangements. The manner of relating the motorto the beater roll shaft renders it possible to satisfy speedrequirements with a small, high power motor and hence provides forgreater economy than can be secured by the use of a directly connectedmotor or a motor geared to the beater roll shaft by a chain or belt.

In considering the appended claims regard must be had of the fact thatvariations in the arrangement, and structure of minor details, may bepracticed without departing from the spirit of the invention.

Having fully described my invention, I

claim rigidly associated with the base, a motor shaft journaled in oneof the standards, bearer arms extending between corresponding standards,the bearer arms being each pivoted to a standard adjacent thereto andhaving their pivots axially coincident with the motor shaft, meansassociated with the other standards and related to the adjacent ends ofthe bearer arms in a manner to produce the raising or lowering of saidarms on their pivots, the bearer arms supporting the beater shaft, andpinion gearing connecting the motor shaft and beater shaft.

3. The combination with a motor and a beater roll shaftof a pair ofbearer arms supporting the beater roll shaft, frames supporting thebearer arms, one of the frames including a standard, the shaft of themotor being ournaled in said standard, and pinion gearing connecting theshafts.

4t. The combination with an electric motor, its shaft, and a beater rollshaft, of end supports for the beater roll shaft, one of the supportsbeing common to the motor shaft, and pinion gearing connecting theshafts.

5. The combination with an electric motor, its shaft, and a beaterrollshaft, of pinion gearing connecting the shafts, and a supportingframe common to the shafts.

6. The combination with an electric motor, its shaft, and a beater rollshaft, of pinion gearing connecting the shafts, and a supporting framecommon to the shafts, the supporting frame including a pivotallyadjustable element to support the beater roll shaft and to maintain thepinions true to their pitch line.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
